LUBRICATOR,

SPECIFICATION forming part of Letters Patent No. 733,179, dated July '7', 1903. Application filedOctober 24, 1902. Ser al No. 128,659. (No model.)

To aZZ whom it may concern:

Be it known that we, GREEVZ FISHER and VARVEL KROSLI, British subjects, and residents of Leeds, in the county of York, England, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to that type of lubricator in which a solid lubricant is forced out from a cup or receptacle by a simple or compound piston or plunger controlled bya spring. It is designed to provide a means to prevent the accidental screwing or unscrewing of the cap or cover or piston-holder or other mobile and operative part of the lubricator by vibration, which may be communicated to it from the bearing upon which it is fixed.

It consists, essentially, of a bar or crosshead, with pin or pins projecting through the operative part to engage holes or notches in the fixed part, the cross-head and pins or either of them being held in position by a spring or springs acting between it and them or either of them and a head or knob on the piston-rod or other abutment attached thereto for the purpose.

The invention will be fully described, with reference to the accompanying drawings.

Figure l is an elevation of lubricator with the invention applied thereto; Fig. 2, an elevation, partly in section, showing the apparatus in a different position; Fig. 3, a plan; Fig. 4, a plan, partly in section; Fig. 5, a plan of lubricator, showing a modification; Fig. 6, a sectional elevation showing the internal piston D, attached to the pin E.

Across the top of the lubricator cover or cap A we place a bar B, held or pressed down against the cover or cap by a spring 0. The bar B slides over a stud or pin E, projecting from the cover A, either attached to the cover or to an internal piston, and the spring is compressed against the head orknob c. From the under side of the bar B project one, two, or more pins 5 to engage the cover A and In the cover A are formed corresponding holes a or notches a, through which the pins 1) project, and in the flange of the body A. are similar holes or notches a When the cover A is screwed down into the cup or body A of the lubricator, the pins Z) of the cross-bar B project through the holes or notches a of the cover into the holes or notches a of the cup or body A, and thereby lock the two together, preventing any rotation of the cover in either direction from vibration or other cause. WVhen the crossbar is raised to the position shown in Fig. 2, the pins 1) are withdrawn from the holes a and also from the holes aand may be rotated at part of a revolution, so that the pins b will rest upon the top of the cover A and maintain the bar in the position shown, Figs.'2 and 3. When in this position, the cap or cover A may be rotated in either direction to screw it into or out of the cup or body A, and when screwed back to the desired position the bar is dropped down again, the pins passing through the holes a and engaging the holes a Referring more particularly to Fig. 6, in which the interior of a lubricator is shown, the internal piston D is actuated by a spring (1 to force the lubricant out, the spring 0 on the top of the cup being weaker than the spring d within it. The cross-bar 3 slides upon the pin E. When the cross-bar B is raised and held up by the pins 1), resting upon the cover A, the internal piston D is also held up within the cup of the cover A, thereby facilitating the filling of the lubricator and the starting of it to work.

Whatwe claim as our invention, and desire to protect by Letters Patent, is-

1. In a lubricator the combination with the body A provided with holes a in the flange, the cover A provided with apertures, and a central pin E, of a cross-bar B placed to slide upon the pin E and extending across the top of the cover, and pins 1) affixed thereto projecting through the apertures in the cover, and engaging'the holes in the flangeofthe body below, to lock the two together to prevent rotation, substantially as described.

2. A lubricator comprising in its construction a body A having holes a formed in the I In witness whereof We have hereunto signed 10 flange, a coverA screw-threaded in said body our names in the presence of two subscribing and having holes a formed therein, a pin E Witnesses.

projecting from the top of cover, a cross-bar 1 5 B provided with central hole through which the pin E passes and placed across the top of the cover A, pins b projecting from the cross- Vitnesses: bar B, through the holes a and engaging the JOSH HY \Vl-IITAKER,
